If you have removed many permissions, tracing which one you removed to cause this issue can take a long time. Fortunately, a short piece of SQL will show you wish permission the system is attempting to find. Run the following against Organisation_MSCRM

Replace ########-####-###-####-############ with the PrivilegeId from the error message, making sure to keep it enclosed in single-quotes. The system will now return the name of the Privilege that CRM requires to display your Entity.
